I bought a 2000 si about a month ago. Its been working just fine but today my engine rpm will not go over 6700. as if my redline fell down to 6500 and the fuel cutoff down to 6700. Anyone have any ideas as to the problem?

don't think the car is overheating. has the fluids in it. i don't have any codes as this happened a little while ago.



Edit.
don't have any codes. i looked for the blue plug with two wires so i can short circuit it and see how many times it blinked. but i'm having trouble finding the blue plug. anyone know where i should look for a 00 so? been looking on the passenger side underneath the glove box

you only do the blink test if you have a check engine light. find out if your car is overheating. having fluid doesnt mean its colling properlly.

yeah man its behind your ecu on the passenger side it should be in a green socket plug thing-a-majig, but the actually two prong plug might be brown,but it might be incased in a green socket plug protector thing, mine was, i think mine is and its a 99 si, but i think the wires that are coming out of it are brown and black/blu :what: its been awhile since i was in the passenger side compartment,lol

if you need more help i will get some pics for you man :thumbs up

thanks for the replies. Found the problem turns our my oil levels where low. And to top it off i found some lubricant in my anti-freeze reservoir. Thinking one of the many gaskets inside the engine is toast. Would that also explain why my oil level is low after driving for about 2 weeks?

If you have oil in your fluid resivior, you probably blew the head gasket.

if i did blow my head gasket would i see a lot of blue smoke coming out? or what would be an easy way to find out without taken it into a shop.

btw thanks for the help. gods knows i knew next to s**t about cars.

by getting into vtec i'm guessing your saying passing 5500ish rpm in normal day driving?
In any day driving. Either way vtec tends to use engine oil quicker but doesnt throw it into your resivoir. Change that head gasket asap.

its not engine oil thats in my reservoir. but lubricant like the stuff found inside a drive axel that is covered with rubber and allows the drive axel turn and spin at the same time. (hope that makes more sense to you then me)

do a compression / leakdown test

check your vtec solonold gasket, and if your head is leaking from the block...there should be low on oil and your block is filled is oil residue, which comes from between the block and the head. when changing gasket you should just change everything. (like head gasket, timing gasket, vtec solonoid gasket, sparkplug gasket, valvecover gasket, etc..) i would if i were to take apart my motor.

redline and VTEC engage are two different things. check your oil cap. if it looks milky, you might have a blown head gasket. and your refering to grease when you talk about the axel lubricant. which btw, how the hell would axel grease be in your reservoir tank?
